Support for partitioned data sets, including PDSE and program libraries, is provided in CA XCOM Data Transport. CA XCOM Data Transport reads the VTOC and the directory blocks to determine whether the file is a PDS and passes this information on to the remote system. When a new file is created on the target system (using the Create File option), CA XCOM Data Transport allocates the same amount of space for directory blocks there as it has on the source system. You can override this allocation by changing the number of directory blocks or reblocking the file through the appropriate File Allocation Information screen (Menu Interface) parameters.
CA XCOM Data Transport transmits aliases if the member to which it is pointed is already on the target PDS.
Checkpointing should not be specified for transfer of PDSs.
Note: CA XCOM Data Transport reads the directory blocks for information such as alias relationships and pointers to preserve the integrity of the data; therefore, PDS files take longer to process than sequential or VSAM files of the same size.
